Said shafts 200 and 208 respectively provided W'th the normally statlanary but rotatahly' adjustable eccentric b arings 201 and 206 so that said shafts may he adjusted in precisely parallel relation with the axis of the printing drum 8, and, it may be observed that such construction not oily simplifies and facilitates the primary assembling of the machine but afiords means to compensate for wear of the respective shafts, aring and rollers.

The mechanism above described. may be operated as follows: The type are in the uesired form in the flexible chase including the parallel channel bars 26 maintained in parallel relation by the flexible bands :27 coini cted with the opposite end ttaching pla es 28 and 29 shown in Fig. ll attached to the drum 8 and covered with the in transfer sheet :30. The sheets of paper 6 of the selected size being directed in the desi ed relation to the width of said type form, the cam 16 is rotatably adjusted on said drum 8 so that when each sheet (3 is presented against the stop lingers 212 it will be gripped at the proper instant to be drawn between said drum and the platen 172 in such relation as to locate the printed impression thereon in the de 1 position with respect to the length of aid sheet. A sheet of paper 6 being then inserted over tne table 7 beneath the guide plate 214 against the stop lingers Q12, and, said drum Sbeing turned in the direction of the arrow marked thereon, said feed roller 203 grips said sheet 6 against the feed roller 200, to draw it between said drum 8 and platen 172. print it, and discharge it over the rollers 221.

I do not desire to limit myself to the precise details of construction and arrangement above described as it is obvious that various modifications may be made therein without 1 invention departing from the essential features of my as definedin the. appended claims.

I claim 1-- l. The combination with a frame, of a printing couple including a rotary drum haying a shaft journaled in said frame, a cam on the end of said shaft outside of the frame, means whereby said cam may be retatably adjusted and secured in rigid relation with saidshaft, paper-feeding mechanism including a supporting table, a. feedroller above said table having a shaft *ith a normally stationary axis, a feed roller below said table, and means arranged to shift said lower roller to and from. cooperative relation with said upper roller, including a rock shaft carrying said lower roller, and an arm rigid on the rock-shaft and located within the frame, and a roller on the outside of the frame coacting with the cam and connected with the arm through a slot in the frame.

The combination with a frame having a pair of upright plates. a shaft journaled in said plates a printing drum on said shaft between said plates. the shaft extending through one of the plates, a cam adjustabl posizioned ontheend of said shaft, a paper table,'a rock-shaft below the table, an arm on sai rock-shaft lying between the frame plates, a roller on the outside of one of the frame plates connected with said arm tirough a slot-.in the plate and coacting with the am, and paper-feed mechanism controlled by said rock-shaft.

in testimony whereof, I have hereunto signed my name at Burlingtmn-New Jersey, this sixth day of September, 1911.
